Polar ice caps on Mars are melting, reports Space.com:
[NASA’s Mars Global Surveyor spacecraft] observed a gradual evaporation of carbon dioxide ice in one of Mars’ polar caps, pointing to a slowly changing Mars climate.
“They way these polar pits are retreating is absolutely astounding,” [geologist Jack] Mustard said.
But like the rockfalls, researchers were unable to account for the gradual climate change.
“Why is Mars warmer today that it was in the past, we really have no way of knowing why,” [scientist Michael] Malin said.
Let’s see:
- Earth getting warmer.
- Mars getting warmer.
- Increased solar activity.
Gotta be those fossil fuels.
